Answer:
1⅞ - 1½ ≈ ½
Step-by-step explanation:
Estimation is mental arithmetic. Practice until you can do this in your head.
Here's one way to estimate with mxed numbers.
Step 1. Separate into whole number and fractional parts
1⅞ - 1½ = 1 + ⅞ - 1 - ½
Step 2. Solve the whole number parts
1 - 1 = 0
Step 3. Solve the fraction parts by estimating.
We will round to the nearest ½, so we should round up a number greater than ¾.
(a) ⅞ is greater than ⁶/₈ (¾), so we round it up to ⁸/₈:
⅞ - ½ ≈ ⁸/₈ - ½
(b) Convert each fraction to a common denominator.
We can write ⁸/₈ as ²/₂
⁸/₈ - ½ = ²/₂ - ½
(c) Solve the fraction part
²/₂ - ½ = ½
Step 4. Combine the whole and fraction parts
0 + ½ = ½
So, 1⅞ - 1½ ≈ ½
Answer:
11≤√134≤12
Step-by-step explanation:
11^2 is 121
and 12^2 is 144
so √134 would have to fall between these numbers
Alrighty mate.
I reckon the answer as hmmm...I'd say<u><em> D</em></u>. All ya gotta do is just cover up the opposite variable and solve for the intercept yar lookin' for.
I hope I helped mate.
Answer:
3/2
Step-by-step explanation:
if you multiply 3/2 by 2 and add 7 you will get 10.
3/2 * 2 = 3
3 + 7 = 10
The answer is 10 x 62. He has 62 across, and 10 vertically. To find how many total he needs, you have to multiply both together. I hope this helps!
